On January 9, the joint prevention and control mechanism of the State Council held a press conference on the relevant information of the tenth version of the diagnosis and treatment plan. Guo Yanhong, director of the Medical Emergency Department of the National Health Commission, said that the diagnosis and treatment plan is a professional and technical standard to guide clinical medical personnel to diagnose and treat people infected with COVID-19, ensure the level of homogeneity of clinical treatment, and ensure the diagnosis and treatment effect. The core idea of the tenth edition of the diagnosis and treatment plan is to manage and treat patients with COVID-19 infection in accordance with the conventional "Class B and Class B" infectious disease management method. After the tenth edition of the diagnosis and treatment plan was issued and implemented, it has aroused widespread concern in the society. In response, Guo Yanhong said that the 10th edition of the diagnosis and treatment plan has mainly adjusted the following contents: First, in terms of admission measures, no centralized isolation treatment is required for cases. People infected with COVID-19 can choose to treat at home or go to medical institutions according to the needs of their illness. Medical institutions at all levels and of all types can receive patients infected with COVID-19. Second, in terms of discharge standards, nucleic acid detection is no longer required. Clinicians can decide whether to discharge the patient after comprehensive study and judgment based on the patient's disease diagnosis and treatment requirements, especially the basic disease conditions and clinical symptoms. "In terms of clinical treatment, first, we need to strengthen the advance of the threshold, and early intervention is also required for mild cases, especially for some elderly patients with basic diseases, we need to strengthen the application of the forward of the threshold measures. Second, we further standardize the diagnosis and treatment of severe patients, and improve the relevant early warning indicators. Third, we adhere to the integration of traditional Chinese and western medicine. Fourth, we have strengthened the concept of co treatment of COVID-19 infection and basic diseases." Guo Yanhong introduced, In terms of diagnostic criteria, the positive antigen test of COVID-19 is included in the diagnostic criteria. The main consideration is that the antigen test has very good detection sensitivity for infected people with high viral load. At the same time, antigen detection is very convenient, simple and easy to carry out, and it is convenient for infected people to conduct self-test at home. Guo Yanhong specially reminded that from the perspective of infected persons, even if nucleic acid is not used, it is necessary to pay attention to personal protection and observation at home after discharge, and it is better not to participate in social activities. To further optimize the "clinical classification", the 10th edition of the diagnosis and treatment plan eliminated the common type and added the medium type. Why did you make such a change? Guo Yanhong pointed out that from the clinical manifestation of the disease, the common type generally represents the most common and typical manifestation of the disease. At present, the virulence of the prevalent Omikjon mutant virus has gradually weakened, and the clinical characteristics of the disease have also changed significantly. Most of the infected persons are upper respiratory tract infections, and the proportion of pneumonia has decreased significantly. Therefore, the common type is canceled and the medium type is added. She introduced that the definition of medium is that the continuous high fever is more than 3 days, and the finger oxygen saturation of breathing air in the resting state is more than 93%. The imaging can see the characteristic manifestation of COVID-19 infection pneumonia, but it is lighter than the severe, that is, the degree of oxygen saturation is less than 93%. According to the 10th edition of the diagnosis and treatment plan, according to the severity of the illness of the infected person, it is divided into light, medium, heavy and critical. "This is more in line with clinical practice, which is conducive to the comprehensive study and judgment of the patient's condition by medical staff and the comprehensive treatment measures," Guo Yanhong said. So, treat COVID-19
